Our 24 inch Vintage Chains really are beautiful. They are the perfect finishing touch to your glass tile pendants, scrabble tiles, bottle cap pendants and other unique pendants you may make.These chains are very nice quality. They don't look chipped or uneven. As with all of our supplies in our shop, we use these same chains in our own business. The oval is approx. 3mmx4mm depending on how you measure. Inside measurement or outside measurement. It is a very nice chain for all occasion pendants. Dress it up or keep it casual - depending on the design of your pendant. � Finishes coordinate nicely with our pendant trays,
